Looking forward, I suspect you are going to have to move to a bcm7445.dtsi with your board specific implementations in something like bcm7445-myrefbrd.dts. It's probably better to split this now to encourage inclusion of the common SoC nodes from the board specific dts. Since it's not abstracted this way it'll encourage people to just copy the entire bcm7445.dts for their board.

These should leverage the preprocessor defines that are available e.g. interrupts = <GIC_PPI 13 GIC_CPU_MASK_RAW(15)|IRQ_TYPE_LEVEL_LOW>, ...
